ADJUSTABLE HOLDBACK.

SPECIFICATION forming part of Letters Patent No. 605,020, dated May 31, 1898.

Application met August 31, 1897. serrano. 650,073. (No model.)

. Io connection to the shafts of a road-vehicle whereby the breech-strap will be held in position for service or use and connected to the shafts in such a manner and by such means as that the breeching may be adjusted and I 5 adapted to any sized animal; and the object is to provide an improved device of the kind named and for the purpose intended which is simple in construction, reliable in use and operation, and which is universally adjust- 2o able in position relatively to the shafts and to the animal.

The invention is fully and clearly illustrated in the accompanying drawings, where- 1n- Fignre 1 is a side view showing the device as applied in actual use'. Fig. 2 is a central longitudinal section through the holdback. Fig. 3 isa detail view of the adj ustableholding-block with swiveledv screw. Fig. 4 is a Awp, detail view of the spring-holding sleeve. Fig.

5 is a side view with the plate removed. Fig. 6 is a plan view of theunderside of the slideplate which is secured to the under face of the shaft, vshowing the pin-holes or sockets in Fig. 7 is a transverse section through the slideplate and top wall of theholdback, showing their flanged connections.. Fig. 8 is a perspective view of one of the holdbacks withy 4o the one end of the breeohing connected thereshafts, to each of which, on the under faces thereof, is secured .a substantial slide-plate 1, formedwith a board track 2, having suitablyflanged edges, Awith which .the counterpart flanges of the holdback engage. These slide- 5o platesareprovided with a series Yof holes ory sockets 3, in which the locking pin or bolt of the holdback engages to lock it in any position desired on the plate. The slide-plates are made of such length as to permit the movement of the holdback for accommodating the breeching to diiferent-sized animals.

B designates the holdbacks, one arranged von each shaft, and consisting of a substantial metal casing of such dimensions as to take in and hold the respective elements essential to effect its practical uses. per wall of the casing are preferably extended, as at 4 4X, and lengthwise in the upper face of the casing is formed a Way or groove 5, having flanged edges adapted to engage with their counterpart iianges on the slide-plates, and thus hold the holdback strongly to the plate. The vertical rear wall 6 of the casing is made thick enough to have formed therein a vertical way 7, in which the locking-pin 8 is disposed. with a stem 9, of smaller diameter than the body of the pin, which stem is projected through and slides in an aperture in the wall 'of the casing and is provided with a leverhandle 10, bent down at about its middle, as at 10X, the inclines of the bent portion engaging in a cam-recess 1l, formed in the bottom end portion of the Casin g. On the stem of the locking-pin within the casing is arranged a spiral spring 12, the force of which holds the locking-pin in engagement with vany hole in the slide-plate and against the force of which the locking-pin may be Withdrawn from such engagement by turning the lever-handle in either direction, when theinclines 10X will ride up the face of the cam-recess 11 and lift the locking-pin, and when the locking-pin is so withdrawn it is held in .such position by the lever-handle resting on the face of the casing, the force of the spring keeping it in that position. When the locking-pin is in the withdrawn position, the casing may be moved in either direction on the slide-plate,

and when in the desired place the lever-han- 9 rIhe ends of the up- This locking-pin 8 is formed4 .A removable plate 13 is secured to the casing loo by means of a fastening-screw taking in a screw-threaded socket 15 in the thick end wall of the casing.

Through the side wall of the easing is projected a bolt 16, extending transversely through the removable plate 13 and held clamped in position by a nut 17 011 its projectin g threaded end, substantially as shown. The nut 17 also firmly holds the plate 13 in place. A washer .17X is shrunk on the neck of the bolt 1G and has its bearing in the wall of the casing. On the inner projecting end of the bolt 1G are formed two iiat lugs or plates 1S 18X, with a space between them, and each provided with a bolt-hole, the two holes registering, and through which ispassed a fastening-bolt 19, for the purpose hereinafter specified. The lower lug orplate 18X is longer than the lug 1S to afford a proper seat or rest for the pivoted or adjustable end of the breech lever or carrier.

2O designates the trace guard or carrier, consisting of an elongated metal frame having a rounded upper end and a fiat or square lower end, which stands upon the upper face of the lug 1S, a fiange 1SC being formed along the lower edge of the base of the carrier and at its rear to set against the edge of the lug and hold the carrier from turning in its seat. The trace is carried through this carrier 2O and is held by it from sagging and vibrating when slack.

2l designates the breeching lever or support, consisting of a substantial plate of metal extending a determined distance to the rear of the holdback to sustain the breeching in proper position and is firmly secured between the plates or layers of the leather composing the breech-strap. The projecting end 22 of this lever or support is curved or bent downward, as indicated, and formed with a lateral fiat lug 223, which is provided with abolt-hole and lies in between the lugs 18 18X, being arranged on the bolt 15), so as to have a limited pivotal movement to permit the breech band or strap to have the requisite play to accommodate it to the lateral motions consequent on the movements of the animal and the shafts.

The stem or body of the bolt 16 is made angular and has removably fitted thereon a metal sleeve 2l, formed with an arm 25, having a lateral lng at its free end formed with a seat in its upper edge or face, in which is anchored and held one end of a strong spiral spring 2G, coiled about the sleeve lc and having its other end extended to reach into and lodge in a notch 27 in the edge of the end wall of the casing. In the free end of the sleeve 2i are cut oppositely-disposed notches 2S, in which lugs 28X on a loose llanged washer 29 engage, the washer 29 having its bearing in a hole in the detachable plate of the easing. This washer 29 sustains and maintains the bolt 16 in horizontal position, and by its engagement with the sleeve is made to turn with it when the levers are moved to higher or lower position. A screw 30 is swiveled through the rear end wall of the casing and carries on its inner portion a cam-block 31, seated on the licor of the casing and formed on its upper face with a plurality of steps 32, on any one of which the end of the arm 25 may lodge, and thus hold the breeching at a higher or lower position. It will be perceived from the foregoing description, taken in connection with the drawings, that when it is desired to carry the breeching at an increased elevation to accommodate it to a tall animal the swiveled screw is turned to withdraw the stepped cam-block 31 from under the arm, and the arm by the tension of the spring is then carried down the incline or steps of the block, and then when the desired height is arrived at the block is screwed into lodgment by turning the swiveled screw, and the breeching will then be securely held against being accidentally lowered. lVhen it is desired to lower the breeching, the lever is utilized to turn the bolt and sleeve, and thus lift the arm of the sleeve to the desired position, and then the stepped block is moved up until the arm lodges on one of the steps, and then, the block being screwed up tight, the arm is firmly fixed in its seat on the block.

The breeching and holdbacks may remain attached to the shafts or they may be removed by withdrawing the locking-pins and sliding the holdbacks off the slide-plates.

lVhat I claim is- 1. In a holdbaek, a easing secured to the shaft, a bolt having a limited rotation transversely projected through the casing and formed with lugs extending at the side of the casing, a breeching, means to hold the bolt in adjusted position against rotation, a leverbar in the end of the breeching and formed with a laterally-extending lug to set between the lugs on the bolt, and a fastening-bolt in the casing and the breech-lever bar.

2. In a holdback, a casing adapted to be secured to the shaft of a road-vehiclefa bolt extended transversely through the casing, a breech-carrier connected to the bolt, a metal sleeve on the bolt formed with an arm, and a spiral spring on the sleeve having one end lodged on the said arm and the other end lodged in the casing.
